This event is needed for clients to handle situations when realms are getting destroyed / removed, eg. closing a frame or tab.

So generally there is no command yet which allows to destroy a specific existent realm. That means realms will be only destroyed when the window object itself gets removed. Hereby I was first thinking about a possible event that we should register for, but we most likely can just rely on the destructor logic of the message handler framework.

That means when the module cache is destroyed it will call destroy() for each module. When the script module removes all the realms we should be able to fire individual events for each of the realms. My hope here is that the event can still be sent to the parent process.
